The main frame of the clock co n-prises a front gupright plate -11 which is preferably constructed from a single piece or sheet of metal, .a .re ;u' .pl ate eonsistingrof an upper section 12 and a Jo ner section lfi haring its upper end ca er-lapping the lower end of the upper section, upper postsl i detaclrahly connected g t their front and rear enc -ls ,by screw i -I l with fi m ines: sail t shahs p e n th mp s id stil s iiiee ss s e li rear-p ele e rests le-sieW-hablrwested e c 1 .1 frent e d ear ends y screw nuts 1. thy -he low slid et-th -fi'wt ismplate an cl th e lou'erend oftheloutea section f the e r n P at and bolts 1.8 sees:- ahly connecting ,lilae pacer-lapping ends of the sections oftherear frame plate,

Adjac-ent to' the striking wheel is arranged the locking wheel 28 which 'is mounted on an axle or shaft29 ournaled in bearings on the front frame plateand the upper section of the rear frame'p'la'te; l

Iifthedowerleft hand part of the main framei's'arrang'edthe spring motor for ope'rating the striking'mechanism, which motor comprise'sa striking motorfshaft or axle 30, a striking s ring 31, and a driving gear wheel 32. The strikingmoto'rshaft is journaled at its 'front" and rear ends in bearings on the frontfram'e plate and the lower section of the" lower section ofthe rear fra1ne "plat e. The'inain striking spring is secured at its oppositefends to the main shaft 30 of the strikingmotor and to the lower section of the rear '"fra'meplate' and the main striking gear wheel 32 is operatively connected with the motor shaft 30, in any approved manner. Motioriis transmitted from the driving wheel of the striking "momma theme 291 of the locking wheel, and the "axle 27 of the striking wheel, by any suitable'foi well known means suchas' the train of gearingfrepresented generally in'Figs. '1' and l bylthej'l'iumeral 33.

Heretofore the'fron't andrear plates of the main frame were each'm'a'de of a single piece of metal, which is "objectionable because this necessitated taking off'the' entire rear plate in 'orderto render the main springs of the striking or time mechanism accessible for re pairing. Suchremoval of the rear frame plate disturbed all the bearings of the important parts 'of the clock such as the striking mechanism and the escapement mechanism and these had to be carefully re-adj usted after the rear frame plate was replaced which involvedundue'loss of time and expense.

By making the rear plate of the frame in sections it is possible to mount the main parts of the clock which do not often get out of order, such as the escapement and s riking mechanisms on one section of the rear frame plate, and the spring motors comprising the main springs and their axles or shafts on another section of the rear frame plate. This renders it possible to detach the rear frame plate section which carries the spring motors from-the companion rear frame section for effecting repairs of these motors and then replacing the samewithout disturbing the bearings of any other parts of the clock mechanism; It follows from this that re-adj ustment of the parts of th'e clock other than the motors Furthermore, bytmaking the -rear frame -.new.eeen e ;weenie-t ends of the same which are detachably -connected iavith each other, the main frame is re-inforced and materially strengthened due to the "double thickness' o'f metal at the joints between the frame plate sections so that the same is not liable to be sprung out ofshape and disengage its-bearings from the-"shafts or axles whichare journaled therein. The frames of clocks as heretofore constructed, were usually so'weak-th'at the saine'would get out of shape'bythe jarring to which they were subjected *during transportation and thismade it frequently necessary for a'retail dealer to repair and re-adjust a clock having sprung frame plates and displ'aced bearings before the "time piece 'was'in condition for, selling to the'trade; Thefpresent construction prevents such springing of themain frame and the loss incident torepairing the same.

In the preferred form of the connection be tween the upper and lower sections of the rear frame plate the'coupling bolts 18 adjacent to the springs 21, 31 of the motors of the time mechanism and striking mechanism are so placed that when these springs expand upon unwinding they will strike these bolts so that the final expansion of-these springs will be directly outwardly and away from the central part of the clock inechanism'and thereby avoid interfering with the latter.

An additionalladvantage in making the rear frame plate in two sections is that small er dies can be employedwhichnot only reduces the cost because they can be made to fit easier, but theycan also be operated with less power.

The trip shaft or axle 24 as'usual is provided with a trip lever or arm 34 which is adapted to "be engaged and shifted by an hour tappet 35 on the center shaft 19, a stop arm 36 mounted on the trip shaft 24 and adapted to be engaged by the stop pins 87 on the locking wheel for effecting a preliminary stop in the rotation of the same, and

at raising arm'38 arranged on the trip shaft and adapted to be raised simultaneously with the stop arm 36. 1

Unwinding of the'strike motor spring 31 is controlled by av counting wheel 39 mounted on the strike motor axle 30 so as to be opera.- tively connected with the inner end of the main striking spring 31 and a counting arm 40 connected with the shaft 25 of the locking mechanism and having a hook 41 adapted to be engaged successively with counting notches 42 arranged in an annular row on the periphery of the counting wheel. This counting arm is disengaged from the counting wheel whenever the strike tappet 35 Brasserie shifts the trip arm 34 "at' which time the raising arm 38 engages the underside of the countingarm and-lifts the-same so that its hook 41 is disengaged from the respective notch 42 of the counting Wheel and permits the-latter to turn under the action of the main striking spring 31. 1 X As the stop arm 36 decends and moves out of the path of the stop pins 37 of the locking wheel 28 the counting arm drops with its hook into engagement With'the next following counting notch 42 and holds the counting :wheel against further rotation, thereafter thelstop pin '37 is engaged by the hook 43 of a locking lever or arm 44 which'is secured to the locking shaftv25 so as to turn therewith, thereby 'holding the locking wheel against rotation and arresting the parts associatedtherewith. w l i 'Between'the' arms and 44 the shaft 25 of the locking mechanism is provided with a controlling arm or lever 45 which has a'hoo'k 46 adapted to engage successively with shoulders 47 formed on diametrical sides of the periphery of the striking wheel or disk 26, for-arresting the rotation of the latter. Whenever the striking wheel is released and turned the same operates the mechanism for sounding the chimes and this in its preferred formis constructed as follows clock mechanism is arrangeda metal chime or bell stand which in the present instance consists of a base 49 secured-to the bottom '48 by a screw 50 and'a standard 51 rising from this base. I I From the upper part of this standard projectsone or more chime'or bell rods52'of diflerent tones which areadap'ted to be struck by a hammer mechanism and thus audibly:announce'the time of the day. In order toprovide a solid and substantial support for these chime rods'the standard is made from a comparatively large mass of metal. However, to permit the chime rods to vibrate more freely when struck a slot or notch 53 is formed on the rear side of thestandard between its upper and lower ends and opening in a direction opposite to the front side of the standard from which the chime rods project. A

This forms a comparatively slender connection between the upper and lower parts of the -standard and causes the chime rods to produce a greater volume of tone than other wise would be the case. Although the chime rods may be mounted on the chime stand in various ways it is preferable to mount the same in the following manner A In the upper part of the standard the same is provided with a'plurality of mounting openings, one for each chime rod, there being two of the latter in the present instance of different length and tone. Each of these sEcT AVAILABLE coPi mounting openings extends through' the standard from its'front side toits' rear side and-consists of a rear part 54 which is cylindrical and a front part 55 which is conical 'and fiares from thecylindricalpart towardly to the front side of the standard: Each chime rod is preferably constructed of metal which is round incross section and thesame comprisesa front body 56 a rear shank 57, and an intermediate n'eck 58 connecting the body and shanka-Thabody' is comparatively long and form'sithe main part of the chime rod. The shank iscomparatively short and is secured in the 'cylindrical part of 'the mounting opening in the stand: The neck of thechim'e' rod is-of conical form and tapers rearwardly from the body of the rod to the shank thereof. At the rear small end of the neck the same isjoi'ned'with the frontend of the shank by an abruptshoulder 59. j i 'By thas makingthfe'front part 5-5 of flat ing or' trumpet shape the' some of the chime rod is spread' ovei the cldck ease and thus increases the volume ofthe s'ameZ By con structing the j motion "of the reduced' neck of the chime rod witlnthe relatively large shank of the same by anabriipt or square shoulder the vihratingcapacitjy "of alarm is increased resulting in'greater resonance of Each of 'the' chime rods is' adapted to be I the rod when thesam'e is struck by a hammer. Ona suitable supportsuch as the bottom 48 of the enclosing-casing of the clock below'the struck adjacent {ta its fixed are by a hani'ih'r mechanism having a'hamn'aer head 60 of metal and a facing 61 ofleather 'oii'said'headwhicli is adapted to" 'hit the chime rod and'thus vibrate the same and'oausing the rod to sound. Each of these hammer heads ismounted on the lower arm 62jof a hammer lever, fthe rear arm 63 of which-is'adapted to 'be engaged by an actuating mechanism whereby this lever is turned iiijthe "direction for raising the hammer and thenlet go s'othat the hammer will descend solely bygravity and strike the respective "chime rod without the aid of springs. By this means the hammer mechanism is materially simplified and the cost of manufacturing reduced. Each hammer lever is preferably made'integr'ally from a single piece of metal wire and the same is mounted between its lowerand upper arms on a hub 64 having 'a"cen'tra'l opening 65 which receives a horizontal pivot pin 66 and thus forms the axis aboutwhich the hammer lever turns. This hammer lever may be secured to its hub in any suit-able manner but preferably by placing this lever in a notch 6? in one side of the respective hub and then securing the'lever inthis notch either by soldering or closing or piiiching the metal of the hub against opposite si'desof the hammer so that the latter is held in the hub by friction. The hubs of both hammer'levers are preferably mounted on the same pivot pin ,66 and the latter is mounted on' a' hanger 68 depending from the lower'part of the lower section" of the l l 1 l ml -1 fit rear (frame plate. The movement of the hammer levers in the direction for engaging the facings of the hammerheads with the chime rods} is-prcferably limited by .a buffer 69 which normally arrests each hammer lever in aposition in- .whiclrit s hammer head is out of contact with the respective chime rod, as shown in lFig.,-l,'but which permits the hammerg 'lever to spring sufiiciently to engage its hammer head WithT-the chime rod and then rebound out et F engagement therefrom'. This buffer. is preferably securedto the-lower part of,the;hange1;58 inpositionto beengaged. by .-the; upper; arm of the respective hammer 'leve p ;,The, arm of each hammer l r: is. P efe ably. a an e n a y n: a horizontal position' or .nearlyso. while-the upper arm;ithereof is.;be nt upwardly into angularformand terminates in the space ad; jacent-to the opposingparts of the timemechanism and striking mechanism motor springs. The motion for; actuating the hammer lever isderived .rrpm the; striking wheel or 'disk 26 and is transmitted fromthe same, to the hammer lever, by two intermediate, levers.

One-10f these intermediate levers comprises; a hub/('0 having an :upper arm 7 1 adapted to be engaged successivelyhy tappet-s or. pins 72 A on diametrically oppositesides of the-front face 1 of. the T striking wheel or; disk 26 and a lo t 'er ilfi havin a l ally P je ti g finger. 7- ns gin Wi lfl PP i 6 f one of hammer levers.

The hubs 7 O, of the two intermediate levers are pivotally mounted zit-their front and rear ends on the front frame plateandjthe upper section of the rear. frame plate. As the striking disk rotates the tappets-on opposite faces thereof deflect the upper arms of the-intermediate levers whichstand in the path of these tappcts and thereby cause the hammer levers to heturnedin the, direction for raising the hammers from the chime rods and when the tappets clear the intermediate leversthe latter are returned to the starting position by the return movement of the hammer levers, thefront arms of which descends under the weight of thehammer heads thereorn.

The relative arrangement of the two sets of striking tappetson opposite faces of the striking wheel is such that two corresponding tappets .on opposite faces of this wheel form a pair and operate their respective hammers one after another so that two strokes, one on one :chime rod following closely after a stroke, on the other chime rod will be given for each hour unit. For example at one BEST AVAILABLE com oclockfa stroke will be delivered against both chime rods but: one after. the other; at two oclock two pairs-of strokes will be: given, the strokes-of each .pair' '-following each other xclosely. and allongerinterval of rest .occuring betweenzsuccessive pairsiofstrokes and so on for each further hour oi the day a 1 1 gulf desired;onpfthechime rods may be sounde'dhy a single :blow to indicatethehalfhour interval =ofatimee -.This is accomplished in i the present icasei by. providing the center shaft 19 withan aifiriliarjycrihalfehour striking tappet diametrically opposite the main or hourly strikingitappet 35, 'which auxiliary Lappelzis adapted-I to engage with an auxiliary upper intermediatearm 81 on the .upper side bfjthe'ihirbls'm and 'raisei-tlie hammer head of the rear -chimeirod;for: producing a single stroke of the respective rodevery-halfhoui'.

Although the chime vor bell rods may be constructed of various metals which may answer the purpose moreor less satisfactorily it is preferable to makethem of 'an alloy having the following constituents in substantiallythe proportions given V Y Y I I Per cent.

- By making the chime rods of the hereindescribedalloy a quality of tone is produced upon striking the rods which is much sweeter and more agreeable than those heretofore known.

I claim as my invention l. A clock comprising two chime rods, two hammer levers each provided with a head adapted to strike one of said rods, two intermediate levers each adapted to actuate one of said hammer levers, and a striking Wheel provided with striking pins on its opposite sides, the pins on each side being adapted to actuate one of said intermediate levers, said hammer levers and intermediate levers turning about different axes.
